PNG to PDF Converter
Convert one or more PNG images into a single PDF document — entirely in your browser, no upload required.
What Is PNG to PDF Conversion?
PNG to PDF conversion takes one or more PNG images and packages them into a single PDF document. Instead of a folder of loose screenshot or graphic files, you get one organized document that's easy to share, print, and archive.
PNG is the format of choice for screenshots, diagrams, and graphics with sharp edges or transparency, so this tool is especially handy for turning a set of screen captures into a shareable report.
Why Convert PNGs to PDF?
PNGs are great for viewing, but they don't page through like a document. Sending ten separate screenshots is messier than sending one PDF, and many places that accept uploads expect a PDF, not a batch of image files.
Combining PNGs into a PDF also locks in their order. A PDF's pages stay in the sequence you set, while a batch of individually attached images can arrive shuffled or out of order.
How This Tool Works
This tool runs entirely in your browser. When you add your PNG images, your device assembles them into a PDF document — all locally, in your device's memory. Your files are never uploaded to any server. Arrange the images in the order you want, and the finished PDF is ready to download in seconds.
PNG vs PDF — When to Convert
PNGs and PDFs serve different purposes. A folder of PNG images is great for viewing and editing individually, but a PDF keeps everything together as a single document. Here is how they compare.
| Feature | PNG Images | PDF Document |
|---|---|---|
| File count | One file per image | Single file for all pages |
| Sharing | Must send multiple files or a zip | One file to email or upload |
| Page order | Depends on file naming | Fixed page order |
| Transparency | Supported | Flattened onto a white page |
| Editing | Easy to crop, resize, adjust | Requires a PDF editor |
Keep as PNG When
- You need to edit individual images — crop, resize, or adjust them
- The image relies on transparency (a logo, an icon, a diagram overlay)
- You want to view and browse images individually in a gallery
- The images are meant for a website, app, or design project
- You only have one or two images that don't need to be combined
Convert to PDF When
- You need to send multiple screenshots or graphics as one organized document
- The images represent pages of a scanned document or form
- You want to preserve a specific page order for the recipient
- A website, portal, or application requires PDF uploads
- You want the images to print consistently on any device
Common Scenarios for PNG to PDF Conversion
Documenting a Bug or Issue
Screenshots are the standard way to show what went wrong in an app or website. Combining a sequence of PNG screenshots into a single PDF creates a clear, ordered report you can attach to a support ticket or send to a developer. If the report is heavier than you'd like, run your screenshots through Image Compressor before combining them.
Submitting Scanned Documents
Many government agencies, banks, and employers require documents in PDF format. If you've scanned your ID, receipts, or forms as PNG images, converting them to a single PDF makes them ready to upload without any hassle.
Sharing Design Mockups
Designers often export mockups, wireframes, or diagrams as PNGs. Combining a set of related screens or slides into one PDF creates a document a client or teammate can page through in order, rather than opening a dozen separate image files.
Building Step-by-Step Guides
Tutorials and how-to guides often rely on a sequence of annotated screenshots. Converting them into a single PDF keeps every step in the correct order and turns loose images into a document that's easy to print or file away.
Sending Screenshots by Email
Email attachments work best with fewer files. Instead of attaching ten separate PNGs to an email, converting them to a single PDF gives your recipient one clean download and avoids the risk of screenshots arriving out of order.
Other Ways to Convert PNG to PDF
You can also create a PDF from PNG using your browser's Print dialog (Print → Save as PDF), or your operating system's own print-to-PDF feature. FileCast is useful when you want a quick conversion without opening a print dialog.
Frequently Asked Questions
Is it safe to convert my PNGs here?
Yes. This tool processes your images entirely in your browser. Your files are never uploaded to any server — everything happens locally on your device. No one else can see or access your images during or after conversion.
Does this tool only accept PNG files?
Yes — this tool is dedicated to PNG files specifically. If you have a mix of formats, including JPG or WebP, use the general Image to PDF converter instead.
What happens to transparent areas in my PNG?
Each PNG becomes a full page in the PDF, so any transparent areas will show as white in the finished document — the same way they'd look if you opened the PNG over a white background. If your image relies on transparency to look correct, consider whether a PDF page is the right destination before converting.
Does the image quality change?
No. Your images are placed into the PDF at their original resolution and quality. The tool does not compress or resize your images — what you see in the original PNG is what you get in the PDF.
How many images can I convert at once?
You can add up to 10 PNG images at once, with each file up to 20 MB in size. The images are processed sequentially in your browser to create a single PDF containing all of them as separate pages.
